entering into the construction thereof,

which include segregated bodies of lubricant, such as graphite. IIitherto,D it has been the practice to support these segregated bodies of lubricant upon perforated or imperforate sheets which were wrapped around the shafts to be borne by the bearing, or about mandrels of the sizes of the shafts and thereafter inclosed in brasses or bodies having bores similar to those of the brasses, whereafter Babbitt or other bearing metal would be poured into the inclosed -spaces surrounding the shafts or mandrels firmly to embed the lubricant bodies in place.

With the devices of thev prior art, the bodies of lubricant were held in fixed and substantially unchangeable distances apart. By means. of my invention, the lubricant bodies may 'have distances therebetween regulated to such an extent as to adapt the lubricant bodies to shafts and brasses of differing diameters, and preferably so that no shaft zone is unencountered by the lubricant bodies, thereby assuring thorough lubrication throughout those shaft lengths that are inclosed'by bearings.

The elementof my invention that enters into the construction of bearings includes av string and bodies of lubricant engaged thereby and distributed in tandem along the length thereof. I use the term string in this description and in theclaim in the sense of a single or multiple stranded long metallic or non-metallic body of suitable cross-section, preferably circular, which is sufficiently exible for the purpose of this invention and which is not formed into a fabric in which the lubricant holding stretches of the component string would be held in substantially fixed relation to hold laterally adjacent lubricantbodies in substantially fixed relation, for if the string were formed into such fabric it would lose its character as a string in the common ac-v ceptation of the term and the cliarcter re\- quired of-it infaccordance'with the present' invention.

I will explain my invention moreifully by reference to the accompanying drawing showing the preferred embodiment. thereof, in Which- Figure l-.is across-sectional View on line llo-f Fig. 2 of a bearing constructed in accordance with the invention; Fig. Q is a longitudinal sectional view of the construction shown in' Fig. 1, a section of the shaft 'being broken away; Fig. 3 illustrates' a length of 91e string with bodies of lubricant material thereupon; and Fig. 4 is a detail view illustrating one step taken in making a bearing.

Like parts are indicated by similar characters of reference throughout the different ligures.

The string-a preferably in the form of wire and is placed in engagement. with the lubricantv 'bodies b, preferably madev of graphite, by having the larger ends of the graphite molded about the same, the graphite bodies desirably being in the nature of truncated coneswhose smaller ends are to be placed next .the shaft e so that the graphite bodies are not liable to be dislodgedfrom the Babbitt metal d in which they are after'- ward embedded, as will appear. The graphite bodies b are distributed along the ,string a, at intervalswhich are preferably regular.

In forming a bearing with the lubricating element of my invention, the string a is pitch of the spiral being desirably such that.'

no shaft zone will be out of contact witha graphite body. The ends of the wire or string may be anchored in any suitable yway. I have illustrated one of two end' plates-e located at the opposite ends of the space to be filled with the Babbitt metal. Each of these plates, which are preferably removable, carries an anchorage screw f about which the wire string is wrapped after it is passed through an opening, in the plate. The brasses g, or other suitable mold for the Babbitt'metal, is located between the plates e, these plates, in addition to holding the ipo opposite endsof the string a, also closingl `my invention, I do not Wish to be limited poured metaljlfinding its way readily between the spaces intervening between the adjacent spiral stretches of string and the lubricant bodies distributed in tandem along the saine anddesirably radially disposed. After the Babbitt or other bearing metal has been poured, the bearing is finished in the usual mannen.

v While I have herein shown and ,partieu lai-ly described the prefererd embodimentof to the preoisel construction shown, but

Having thusy described my invention, I

claim as new and desire to secure by Letters i Patent the Following:l l

A bearing including a shaft; a body k1n` which said shaft is journaled; portions of lubricating material; a body in Which said portions' of lubricating material are embedded; and a string spirally Wound about the shaft, said string being engaged by said portions of lubricating material that are spaced apart in tandemualong the string.

In Witness whereof, I'hereunto subscribe my name this 8th day of July, A. D., 1910.
